This invention relates to trunk locks, and has for its object to provide a simple and eitfectiye lock which can be used in connection with any hasp member so long as the latter carries suit-able cooperating lockable means.

This invention relates solely to the lock feature which cooperates with one or more hook-like members carried by the usual hasp.

In the accompanying drawings,

Figure 1 is a ront elevation showing the appearance ot the trunk lock as a whole when the parts are closed and in locked condition- Figure 2 is a section at the line 2-2 of Figure 1, with the hasp closed and locked- Figure 3 is a View similar to Figure 2 but showing the position of parts when the hasp is thrown open- Figure el. is a i'ront elevation similar to Figure 1 but showing the liasp member thrown upwardly to a horizontal position- Figure 5 is a detail elevation of the key- Figure 6 is a view of the lower part of the escutcheon plate partly broken away to show the lock casing and the parts therein when they are in locked condition- Figure 7 is View similar to Figure 6 showing the parte within the casing as they appear after the tumbler has been acted upon by the key and immediately prior to the withdrawal oic the locking bolts- Figure 8 is a View similar to Figures 6 and 7, but showing the position of the parts ot the lock when the key has been operated to place the tumbler in position immediately preparatory to the shooting'ot the bolts of the locking plate into locking engagement- Figure 9 is a view similar to Figures 6, 7 and 8, but showing trie position of parts when the locking bolts have been retracted, and

Figure 10 is a side elevation ot the lock escutcheo-n plate with the hasp forced inwardly, the parts being` partly broken away to show the lockable member carried by the hasp engaged with the bolt.

Similar numerals ot reference denote like parts in the several figures of the drawing.

portions hooks 5 which extend inwardly and are adapted to be engaged within slots 6 1n an escutcheon plate 7 secured to the tace ot the trunk body.

To the inside of the escutcheon plate is secured the lock casing 8, and Ouided within this casing is a tumbler 9 and on the outside of this tumbler and likewise guided within the casing is a lock plate 10 which has a tail portion 11 that is guided through an opening 12 in the lower wall of the casing, while from the upper end of the plate 10 project bolts 13.

'As before stated there are two of the hooks 5 that project inwardly from the sides of the hasp Ll, which hooks, when the hasp is forced inwardly enter the slots 6 in the eseutcheon plate and are then in position to be engaged by the bolts 13.

Assuming that the hasp has been forced inwardly to bring the hooks 5 in proper locking position, the key 14 is inserted through a key slot 15 in the tace of the plate 7, this slot being formed within the usual rotary barrel 16, and the lock is operated in the ina-nner which will now be described.

rlhe tumbler 9 has spaced lugs 17 which eze tend outwardly from what will be termed the inner edge thereof, while the lock plate 10 has spaced lugs 18 that extend from the inner edge of the plate,- and these lugs 17, 18, are interengageable in thek Jfollowing manner 19 is a spring member confined between the edge of the lock casing and the inner edge of the tumbler the function of this spring being` to normally thrust the tumbler outward# ly to the position shown at both Figure 6 and Figure 9, in which position the tumbler lugs 17 are engaged in abutment immediately beneath the lugs 18 of the lock plate so as to vprevent the retraction of the latter from the locking position in which it shown at Figure 6, while at Figure 9 the lugs 17 are engaged with the lugs 18 immediately above the same to prevent the locking plate :trom being tirown into locking position except by the Referring to Figure S, when the ltey is operated its wards primarily thrust the tumbler 9 to one side, against the resiliency of the spring 19, so that the lugs 17 will be clear ot `30 gates therein within which the bolts of the 35 tual gates, is illustrated in the instance of the the lugs 18, and the final movement of the key ment of the tail lugs with the upper faces of will then shoot the bolts 13 into locking enthe tumbler lugs.

gagement with the hooks 5, and as soon as the In testimony whereof I aiix my signature lugs on the locking plate pass above the lugs hereto.

on the tumbler the locking will have been e- ALBERT J. KOMENAK. 70 fected, and the spring 19 will then force the tumbler to normal position with its lugs 17 engaging immediately below the lugs 18 of the lock plate so as to prevent the retraction of the latter except by the use of a key, as 75 shown at Figure 6.

In unlocking a similar action occurs, the key being, of course, turned in a reverse direction, and the first movement of the key will 15 cause its wards to act against the tumbler and thrust the latter to one side so that its lugs 17 will be clear of the lugs 18 on the locking plate, as shown at Figure 7, and the continued movement of the key will then retract the 20 bolts 13 and cause the lugs 18 to be thrust 85 downwardly in a plane below'that of the lugs 17, whereupon the action of the spring 19 will force the tumbler into its normal position with the lugs 17 engaged with the lugs 18 immediately above the latter so as to prevent the shooting of the bolts upwardly without the use of the key, as shown at Figure 9.

It will, of course, be readily understood that the hooks 5 need not have any actual lock plate can engage, since it is merely necessary that these bolts should be shot over a surface carried by the hasp, and a simple engaging member of this sort without any acsingle hook member shown at Figure 3. For

all practical purposes the members 5 may be designated as lockable members.

What is claimed is 40 A trunk lock, comprising a hasp member pivotally swung from the trunk lid and carrying at its outer extremity spaced inwardly extended open gated members, an escutcheon plate secured to the trunk body and having` spaced openings in its lower portion adapted to receive said gated members when the basp is swung downwardly to locking position, a casing within said portion and secured to said escutcheon plate, a spring actuated tumbler slidably guided within said casing 115 and having at its inner edge spaced outwardly projecting lugs, a locking member having a tail portion that is guided through the lower wall of said casing and is adjacent to and rests upon said tumbler, said locking member having bolts which are spaced to correspond to the spacing of said openings in said escutcheon plate, and said tail portion having lugs that extend horizontally from its inner edge to abut the lower faces of the tumbler lugs when said bolts are retracted, said tumbler being adapted to be thrust away from said tail by a key thereby disengaging said lugs and causing said bolts to engage within said gated members and effecting the engage-
